Slower walkers have older brains and bodies at 45

Slower walkers have accelerated aging in middle age, both physically and cognitively. Tests given to measure IQ, language, motor skills, and emotional control at age 3, can predict walking speed and thus accelerated aging during middle age.

Navigating ‘Neuralville’: Virtual town helps map brain functions

Combining neuroimaging and a constructed virtual reality town, researchers found the brain uses three different systems to perceive environment. One system allows us to recognize a place, another helps navigate through that location, and the third helps navigate from one place to another. The parahippocampal place area (PPA) helps encode location recognition, while the retrosplenial complex allows for mentally mapping the locations of specific places.

Promising steps towards hope for a treatment for schizophrenia

Mu-opioid receptor (MOR) levels are significantly reduced in the striatum in those with schizophrenia. A lack of MOR system stimulation contributes to negative feelings, such as a lack of motivation and anhedonia, associated with the condition. Increasing MOR levels could help to reduce some of the symptoms of schizophrenia.

The propensity to hear ‘voices’ in Schizophrenia may be established by infancy

People with schizophrenia who experience auditory hallucinations have greater activation in specific areas of the auditory cortex in response to sound frequencies. The mapping of sound frequency in the auditory cortex is scrambled in those with schizophrenia, suggesting a disruption in the normal processes for organized sound representation in the brain. As the tonotopic map is established during infancy and remains stable throughout life, the findings suggest vulnerability for auditory hallucinations is linked to defects in the organization of the auditory system during infantile development. This precedes speech development and the onset of psychiatric symptoms.

Male/female differences in the development of brain hubs involved in memory and emotion

A new neuroimaging study reveals sex-based differences in the development of the hippocampus and amygdala. The findings may shed light on sex-based differences in the emergence of mental health disorders the occur during adolescence and early adulthood.

Neuroimaging reveals hidden communication between brain layers during reading

Stronger activation for words over pseudo-words was seen in deep layers of the visual word form area. The activation caused top-down projections from higher language areas of the brain.
